HUMAN MACHINE INTERFACE PRODUCTS

With over 40 years of design and manufacturing experience, our products perform the most challenging requirements of air transport, business aviation, military programs, and now space with the Orion Spacecraft.

Human Machine Interface products are used throughout the cockpit to provide information and control of aircraft systems. Our illuminated products offer this capability for both day and night operations and can be adopted for use in night vision applications (NVG / NVIS).

Whatever the name … you can rely on Spectralux Avionics as your affordable, dependable, and responsive partner.

LIGHTPLATE AND KEYBOARD DETAILS

AMONG THE MOST COMMON HMI PRODUCTS

Lightplates and Keyboards are among the most common HMI products integrated into the cockpit directly or as part of another aircraft system. These specialized products are highly engineered and defined by common industry accepted performance characteristics. While the following general specifications are frequently requested, there are often cases when mission specific requirements are needed. Spectralux Avionics is here to help with your needs … standard or uncommon.
